IMPROVEMENT IN MACHINES FOR SIZING CORKS.

Specication forming part of Letters Patent No. 154,887, dated September 8, 1874; application filed July 18, 1874.

To all whom 'It may concern:

Be it known that I, NOAH WILLIAM MITCH- ELL, of Southsea, in the county of Southampton, England, have invented an Improved Machine for Sizing Corks, or for separating and distributing the different sizes of corks or other articles, of which thefollowiug is a specification:

This invention consists of an improved machine for sizing or sorting corks or other articles to be sorted.

The following is a description of my said invention for sorting corks, reference being had to the illustrative sheet of drawing hereunto annexed. I

Figure l represents a sectional elevation through the line'A B of Fig. 3. Fig. 2 represents a sectional elevation through the line C D of Fig. 3. Fig. 3 is a plan of the machine. Fig. 4 is a view showing a different way of working the levers.

In these ligures similar letters of reference denote corresponding parts.

A quantity of corks, of mixed sizes, is put into the hopper A, the lower end of which opens into the wooden tray B, which is kept full of corks. The operator puts the corks into the feed-tnbe C, under which is a revolving disk, D, containing a series of boxes, E. Each of the boxes E is itted with a lever, F, either horizontal, Figs. 1, 2, and 3, or perpendicular, Fig. 4, one end of the lever G being forced into the box E by means of a spring or weight, f. As each of the boxes Er approaches the said feed-tube C the other end of the lever H comes into contact with an opening-cam, J, by which the end of the said lever G is withdrawn out of the box E. As soon as the box E has passed under the aforesaid feed-tube C and received a cork one end of the lever G then enters the box E and holds the cork against the end thereof, and the other end of the lever H projects more or less, according to the diameter of the cork. As the box E revolves that end of the lever H strikes against one of the graduated gages L, and the cork falls into one of the chutes M. An adjustable table, N, is placed below the revolving disk D, and exactly under the feedtube C, for the cork to rest upon until carried away by the box E. Attached to the feed-tube G are checks V G and the opening-cam J belonging to it, the

machine is converted into asingle one, giving double the number of divisions of the sizes.

I propose to work-the said machine by means of a treadle very similar to that of a sewingmachine or other suitable motive power.

I claim as my invention- The machine by means of which corks or other articles of different sizes may be sifted or sized, constructed substantially as above described and represented.

N. W. MITCHELL.
